// USGS Greenness Web Service Query Tool 
// Created By:  Chris Rusanowski
// Installation:
//   -Copy USGS_Greenness_Service.js into the javascript directory of the HTML Viewer
//   -Include the javascript/USGS_Greenness_Service.js in MapFrame.htm 
//      <script type="text/javascript" language="JavaScript" src="javascript/USGS_Greenness_Service.js"></script>
//   -Add a button to the toolbar.htm that calls parent.MapFrame.setGreennessTool().
//     (Actually add a button to USGS_Toolbar.js... The code below is and example from that JS file.)
//      if (parent.MapFrame.useGreennessService)  { miscCount++; }
//        if (parent.MapFrame.useGreennessService) {
//          if (parent.MapFrame.modeName == "Greenness") {
//            LocalString += WriteButton( MakeButton2( "usgs_images/Greenness1.gif", 'Greenness Query Tool', "Greenness", "parent.MapFrame.modeName=\'Greenness\'; parent.MapFrame.setGreennessTool();", 'status=\'Greenness Query Tool\'', "", true ) );
//          } else {
//            LocalString += WriteButton( MakeButton2( "usgs_images/Greenness2.gif", 'Greenness Query Tool', "Greenness", "parent.MapFrame.modeName=\'Greenness\'; parent.MapFrame.setGreennessTool();", 'status=\'Greenness Query Tool\'', "", true ) );
//          }
//          buttonCol++;
//          LocalString += Table_Structure(buttonCol,miscCount);
//        }
//   -Add code below to aimsCustom.js so the map tool functions...
//      if (toolMode == 1090) { 
//        getGreenness(e);
//        return false; 
//      }
//   -Copy the getGreenness.php file into the main HTML viewer directory 
//     (IE: same directory mapframe.htm is in...)
//   -Copy the Greenness1.gif and Greenness2.gif into the usgs_images folder.
